Mariano Rivera’s son, Iona College right-hander Mariano Rivera Jr., was drafted by the Nationals in the fourth round. He was previously drafted by the Yankees in the 29th round last year and decided to go back to school for another season, which worked out pretty well.

Rivera Jr. doesn’t throw a cutter, which seems like a shame, but he does have a fastball that reaches the mid-90s and what James Wagner of the Washington Post describes as a “power slider.”

The fact that Mariano’s kid is as good as he is right now, I’m sure his father had a lot to do with that. He has the genes there. He’s not a tall kid, but he’s got big shoulders, long arms, big hands, and that really helps as far as the durability for his size.

Rivera Jr. figures to sign for around $400,000 and told Wagner he doesn’t regret not ending up with the Yankees because “any team that picked me, I’d be loyal to them.”

One day after placing left-hander Andrew Miller on the disabled list with a strained forearm muscle Yankees general manager Brian Cashman indicated that he expects the closer to miss around one month.

Cashman told Anthony McCarron of the New York Daily News that Miller will be completely shut down from throwing for two weeks before resuming a throwing program, leaving stud setup man Dellin Betances as the Yankees’ closer for the remainder of the first half.

Miller converted 17 saves with a 1.03 ERA and 43 strikeouts in 26 innings while holding opponents to a .090 batting average in the first season of a four-year, $36 million deal signed this winter.
